Protesters attack a riot police bus in central Kiev, Ukraine, Sunday, Jan. 19, 2014. Hundreds of protesters on Sunday clashed with riot police in the center of the Ukrainian capital, after the passage of harsh anti-protest legislation last week seen as part of attempts to quash anti-government demonstrations. A group of radical activists began attacking riot police with sticks, trying to push their way toward the Ukrainian parliament building, which has been cordoned off by rows of police and buses.
